GATE.

SPECIFICATION forming part of Letters Patent No. 404,754, dated June 4,1889.

Application filed eptember 21, 1888. Serial No. 286,045. (No model.)

To all whomit may concern.-

Be it known that I, JOSEPH XVALKER, a citizen of the United States ofAmerica, residing near Manchester, in the county of Chesterfield andState of Virginia, have in vented certain new and useful Improvements inGates, of which the following is a specification, reference being hadtherein to the accompanying drawings.

This invention pertains to certain new and useful improvements in gates,having for its object the provision of a new and improved highlyefficient gate composed of pivoted members and capable of being raisedor lowered from either side into a vertical or horizontal position, andrigidly held or secured as against accidental displacement.

This invention therefore comprises the details of construction,combination, and arrangement of parts, substantially as hereinafterfully set forth.

In the accompanying drawings, Figure 1 is a view in perspective of 'myimproved gate. Fig. 2 is a sectional detail View thereof.

Referring to the drawings, .A designates my improved gate, which iscomposed of an upper extended right-angular beam a, to which arepivotally secured the upper ends of hangerbars a, and to these bars aare pivotally connected a series of parallel cross-bars (L2, as shown.These parts are so constructed and arranged that the cross bars a willfold against the beam at when the main portion thereof occupies avertical position.

B B are two parallel posts, between which the inner ends of cross-bars aextend, while the outer ends of said cross-bars are designed to passbetween two similar posts I) b.

To either side of the right-angular beam at are secured plates 1) I),provided with slots 5 through which bolts are passed. By means of theseslots and bolts said plates can be adjusted and secured at the desiredpoint.

The gate is pivoted upon the posts B B by' means of a short spindle orcross-rod 0, passed through apertures of plates 1) and resting ingrooves or recesses formed in the tops of said posts. The gate A and itsbeam a are equally balanced, so that the same can be readily raised andlowered. By shifting the fulcrum of beam a the center of gravity can beTo a cross-piece d of these posts D is pivotally secured one end of aright-angular gravity-latch E, the main arm d of which extends down tonear the end of posts D, and is provided with two grooves or recesses dd for engaging beam at, the former for holding the gate down or closedand the latter for holding it up or opened.

- F F are two levers centrally fulcrumed upon posts ff, and to theirinner ends are secured pitmen or links f f, which are secured by boltsto the gate A.

To the outer ends of these levers F F are connected ropes or chains G G,each of which is passed over a roll g, attached to a short post g, andafter being passed around rollers g g of a latch-operating bar H issecured at its ends to levers h h, fulcrumed upon a post h". From theouter ends of these levers h h depend short ropes or straps b If.

The latch-operating bar H above referred to is pivotally secured at 72,to the gravitylatch E, and is passed through looped ends of straps orwires I I, depending from short arms z" 71 of posts 6" 2'". To the outerends of this bar H are secured short parallel strips '6 7?, betweenwhich the rollers g g revolve.

From the foregoing description it will be seen that by grasping the ropeor strap 71 of lever h and pulling downward thereon the other end ofsaid lever will pull on rope or chain G, and thus lower the outer end ofthe adjacent lever F and cause the elevation of gate A into a verticalposition. When the lever h is being operated upon, the rope or chain Gwill cause the latch-operating bar H to move, and thus the groove orrecess (1 of the latch E is disengaged from the beam a and the same isfree to move, and when its outer right-angular portion reaches theextent of its movement the groove or recess 61 of latch E will engagethe same by gravity and hold the gate elevated in a vertical position.

It is obvious that after the operator has passed to that side of thegate opposite to the one upon which he opened or raised the gate bypulling upon the lever h the gate can be lowered to its former position,the movement of said lever causing the gravity-latch to be disengagedfrom the gate through the agency of bar H. By moving the looped ends ofstraps or wires I in either direction the same will efiect the movementof bar H to a greater or less degree, as desired.

The parts of my gate are so arranged that the beam a is equallybalanced, so that it can be easily and readily raised or lowered withoutany unnecessary labor and without fear of damage. when the gate iselevated or in a vertical position, these plates 1) can be adjusted, ifdesired, by simply loosening and then tightening the bolts 1)".

My invention, in addition to the foregoing advantages, is extremelysimple, cheap, and durable, and it will be seen that the same embodiesfurther advantages in point of general efficiency and inexpensiveness.

I claim as my invention- 1. As an improvement in gates, the hereimdescribed gate having the upper pivoted righ tangular beam, the postsbetween which said beam operates, and the gravity-latch pivotallysecured to one of said posts and having grooves or recesses engagingsaid beam, substantially as set forth.

2. The gate having the upper pivoted beam, the posts D D, between whichsaid beam operates, the pivoted gravity-latch secured to one of saidposts," and the latch-operating bar pivotally secured to said latch andloosely supported in position, substantially as described.

3. The gate having the pivoted beam, the posts D D, between which saidbeam operates, the latch pivotally secured to one of said posts, theoperating-bar pivotally secured thereto, and the ropes or chains foroperating said bar, substantially as described.

4. The gate having the pivoted beam, the posts D D, between which saidbeam operates, the levers F F, secured to said gate at their inner ends,the gravity-latch pivoted to one of said posts, the operating-barpivoted to said latch, the levers h 71 and the ropes or chains connectedto said latterlevers and the levers F F, substantially as described.

5. The combination, with the gate having the pivoted beam and the postsD D, between which said beam operates, of the latch pivoted to one ofsaid posts, the operating-bar pivoted to said latch, the guide-loops forsupporting said bar, and the means for operating the latter at its outerends, substantially as set forth.

In testimony whereof I allix my signature in presence of two witnesses.

JOSEPH \VALKER.
